Armoy native Hannah Craig (27) qualified for London 2012 at the European Championships in Germany on 11 May 2012.
Two spots at the Games were available to nations who had not qualified through the World Championships last year.
Craig's 25th place at the Europeans was enough to secure her ticket for London.
Craig was raised in France where she got the canoeing bug and narrowly missed out on qualification for Beijing.
She formed her own clothing company to help fund her Olympic qualification effort.
She is now largely based in Belfast with her coach Han Binjen.
Binjen worked with Team Ireland at the Beijing Games.
First in action on 30 July in the heats. Start time is 1.30pm.
